Answer:

Angle A =35 degrees, Angle B = 90 degrees, and Angle C = 55 degrees

Step-by-step explanation:

So all the angles added up would be 180. Let's use the variable x. The angles would be 7x, 18x, and 11x.

The smallest angle is 35, and 7x is the smallest out of all them since x has to be positive.

7x = 35

x = 5

Then substitute x into each angle.

They would be 35 degrees, 90 degrees, and 55 degrees

Answer:

A. the probability that the sum is 11,given that the first number cube shows a 6

The correct answer is the probability that the sum is 11, given that the first cube shows the number 6.

Conditional probability is defined as the likelihood of an event or outcome occurring, based on the occurrence of a previous event or outcome.

Let A and B be two events as given.

B|A = "Event B given Event A"

In other words, the probability Pr(B|A) says "event A has already happened, now what is the chance of event B"

P(B|A) is also called the "Conditional Probability" of B given A.

In our case, the probability Pr(B|A) represents "the probability that the sum is 11, given that the first cube shows the number 6".

Hence, the correct answer is the probability that the sum is 11, given that the first cube shows the number 6.

Answer:

$58.61

Step-by-step explanation:

So easily

the mark down is 71 percent or 0.71

Techinacially your just paying 29 percent of the product becuase 71 percent is gone

So just multiply 0.29 by 202.11

You’ll get 58.61 as the final sale price

If you do it the hard way, still the same answer

Answer: $58.61

Step-by-step explanation:

Markdown: 71% × 202.11

0.71 × 202.11 = 143.4981

143.4981 ≈ 143.50

Markdown ≈ $143.50

Sale price: Original price - Markdown

$202.11 - $143.50 = $58.61

Sale price ≈ $58.61

Answer:

[tex]m = -\frac{2}{5}[/tex] ---- slope

[tex]y = -\frac{1}{3}[/tex] --- y intercept

Step-by-step explanation:

Given

The attached table

Required

Calculate the slope and y intercept

First, we need to calculate the slope

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

From the table, the following relationships exist:

[tex](x_1,y_1) = (-\frac{3}{4},-\frac{1}{30})[/tex]

[tex](x_2,y_2) = (\frac{1}{4},-\frac{13}{30})[/tex]

So, the expression for calculating slope becomes:

[tex]m = [-\frac{13}{30} - (-\frac{1}{30})] / [\frac{1}{4} - (-\frac{3}{4})][/tex]

[tex]m = [-\frac{13}{30} +\frac{1}{30}] / [\frac{1}{4} +\frac{3}{4}][/tex]

Take LCM

[tex]m = [\frac{-13+1}{30}] / [\frac{1+3}{4}][/tex]

[tex]m = [\frac{-12}{30}] / [\frac{4}{4}][/tex]

[tex]m = [\frac{-12}{30}] / 1[/tex]

[tex]m = \frac{-12}{30}[/tex]

[tex]m = \frac{-2}{5}[/tex]

[tex]m = -\frac{2}{5}[/tex]

To calculate the y intercept:

x must be 0. i.e.

[tex]x = 0[/tex]

So, we have:

[tex](x_1,y_1) = (-\frac{3}{4},-\frac{1}{30})[/tex]

[tex](x_2,y_2) = (0,y)[/tex]

[tex]m = -\frac{2}{5}[/tex]

Substitute these values in:

[tex]m = \frac{y_2-y_1}{x_2-x_1}[/tex]

[tex]-\frac{2}{5} = [y - (-\frac{1}{30})] / [0- (-\frac{3}{4})][/tex]

[tex]-\frac{2}{5} = [y +\frac{1}{30}] / [0+\frac{3}{4}][/tex]

[tex]-\frac{2}{5} = [y +\frac{1}{30}] / [\frac{3}{4}][/tex]

Multiply through  by 3/4

[tex]-\frac{2}{5}*\frac{3}{4} = y +\frac{1}{30}[/tex]

[tex]-\frac{6}{20} = y +\frac{1}{30}[/tex]

[tex]-\frac{3}{10} = y +\frac{1}{30}[/tex]

Collect Like Terms

[tex]y = -\frac{3}{10}-\frac{1}{30}[/tex]

[tex]y = \frac{-9-1}{30}[/tex]

[tex]y = \frac{-10}{30}[/tex]

[tex]y = \frac{-1}{3}[/tex]

[tex]y = -\frac{1}{3}[/tex]

Answer:

2/3

Step-by-step explanation:

16/24 = 14/ 21 = 12/ 18 10/ 15 8/12 6/9 4/6 = 2/3

The simplest form of the number 16.24 in fraction would be 406/25.

Used the concept of fraction which states that,

A fraction is a part of the whole number and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called a fraction. It can be written in the form of p: q, which is equivalent to p / q.

Given that,

The number is 16.24.

Now, it can be written as,

[tex]16.24 = \dfrac{16.24 \times 100}{100}[/tex]

[tex]= \dfrac{1624}{100}[/tex]

Therefore, the simplest form is,

[tex]= \dfrac{406}{25}[/tex]
